FC connectivity FAS2552 with VMware ESXi 5.5 not work

‎2017-03-1008:10 AM

Hello,I have a NetApp/VMware infrastructure. The NetApp storage disk is FAS2552 C-mode 8.3.The connections between FAS2552 and VMware ESXi are fibre channel (with QLogic SANbox 5802 switchs).There are one ESXi in version 4.1 and 5 ESXi in version 5.5, in a other cluster.The ESXi 4.1 can connect to FAS2552’s LUNs. But all ESXi 5.5 cannot connect to same LUNs.I do not find the reason.The configuration is the same for LUNs and zonning. And “fcp ping” command returns “is alive” for all initiators.
